Study Notes
Remainder Theorem
- When dividing a polynomial function p(x) by x-a, the remainder r is found by evaluating p(a).
Factor Theorem
- A polynomial f(x) contains a factor (x-k) if and only if f(k) equals zero. This signifies k is a root of the polynomial.
Rational Root Theorem
- For a polynomial p(x) with integer coefficients, any rational root can be expressed as p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.
Irrational Root Theorem
- In a polynomial p(x) with rational coefficients, if a root takes the form a+b√c (where a and b are rational, and √c is irrational), then its conjugate a-b√c is also a root.
Number of Roots Theorem
- A polynomial of degree n possesses exactly n roots, considering both real and complex roots.
Fundamental Theorem of Algebra
- Every polynomial function has at least one complex zero, which may be real or non-real.
Complex Conjugate Theorem
- If a polynomial contains complex roots, they occur in conjugate pairs; if 2-i is a root, then its conjugate, 2+i, must also be a root.
Location Principle
- If a polynomial function p takes on opposite signs at two points, p(x1) and p(x2), then there exists a real number r between x1 and x2 where p(r) equals zero, confirming that r is a root.
